People can’t anticipate how much they’ll miss the natural world until they are deprived of it. I have read about submarine crewmen who haunt the sonar room, listening to whale songs and colonies of snapping shrimp. Submarine captains dispense “periscope liberty” - a chance to gaze at clouds and birds and coastlines - and remind themselves that the natural world still exists. I once met a man who told me that after landing in Christchurch, New Zealand, after a winter at the South Pole research station, he and his companions spent a couple of days just wandering around staring in awe at flowers and trees. At one point, one of them spotted a woman pushing a stroller. “A baby!” he shouted, and they all rushed across the street to see. The woman turned the stroller and ran. Nothing tops space as a barren, unnatural environment. Astronauts who had no prior interest in gardening spend hours tending experimental greenhouses. “They are our love,” said cosmonaut Vladislav Volkov of the tiny flax plants - with which they shared the confines of Salyut 1, the first Soviet space station. At least in orbit, you can look out the window and see the natural world below. On a Mars mission, once astronauts lose sight of Earth, they’ll be nothing to see outside the window. “You’ll be bathed in permanent sunlight, so you won’t even see any stars,” astronaut Andy Thomas explained to me. “All you’ll see is black.”

This is a really interesting read - it’s got a lot of information that I would never have thought to think of (such as - will astronauts eyeballs become different shapes without gravity - weird), but it also has really good chapters about the psychology of space.

this is wonderful - and def something I've thought about!

Lockheed Martin joins the space race to Mars

From China to NASA to Elon Musk, it seems everyone has their sights set on Mars exploration. But before we land on the Red Planet, we’ll probably orbit it. At this week’s Humans to Mars summit, Lockheed Martin unveiled its Mars Base Camp concept — an ambitious plan to send a manned space laboratory to orbit Mars by 2028.

lol omfg yes

First flower ever grown in space bloomed today!

New HiRISE Images

NASA’s HiRISE mission has just released an amazing swathe of new images of the Martian surface.

This mission’s a personal favorite as their images have been detailing Mars in an almost “Google Earth” manner of beauty. From the Martian sky you can see the dunes, craters and other features that litter the landscape, revealing the clues that detail the mysterious story of Mars.

See the images here!

Living and Working Aboard Station

 Join us on Facebook Live for a conversation with astronaut Kate Rubins and the director of the National Institutes for Health on Tuesday, October 18 at 11:15 a.m. ET.

Astronaut Kate Rubins has conducted out of this world research aboard Earth’s only orbiting laboratory. During her time aboard the International Space Station, she became the first person to sequence DNA in space. On Tuesday, she’ll be live on Facebook with National Institute of Health director Francis Collins, who led the effort to map the human genome. You can submit questions for Kate using the hashtag #SpaceChat on Twitter, or during the live event. Here’s a primer on the science this PhD astronaut has been conducting to help inspire your questions: 

Kate has a background in genomics (a branch of molecular genetics that deals with the study of genomes,specifically the identification and sequencing of their constituent genes and the application of this knowledge in medicine, pharmacy,agriculture, and other fields). When she began her tenure on the station, zero base pairs of DNA had been sequenced in space. Within just a few weeks, she and the Biomolecule Sequencer team had sequenced their one billionth base of DNA aboard the orbital platform.

“I [have a] genomics background, [so] I get really excited about that kind of stuff,” Rubins said in a downlink shortly after reaching the one billion base pairs sequenced goal.

Why is DNA Sequencing in Space a Big Deal?

A space-based DNA sequencer could identify microbes, diagnose diseases and understand crew member health, and potentially help detect DNA-based life elsewhere in the solar system.

NASA and Its Partnerships

We’re not doing this alone. Just like the DNA sequencing was a collaborative project with industry, so is the Eli Lilly Hard to Wet Surfaces investigation. In this experiment aboard the station, astronauts will study how certain materials used in the pharmaceutical industry dissolve in water while in microgravity. Results from this investigation could help improve the design of tablets that dissolve in the body to deliver drugs, thereby improving drug design for medicines used in space and on Earth. Learn more about what we and our partners are doing:

Researchers to Test How Solids Dissolve in Space to Design Better Tablets and Pills on Earth

With our colleagues at the Stanford University School of Medicine, we’re also investigating the effects of spaceflight on stem cell-derived heart cells, specifically how heart muscle tissue, contracts, grows and changes  in microgravity and how those changes vary between subjects. Understanding how heart muscle cells change in space improves efforts for studying disease, screening drugs and conducting cell replacement therapy for future space missions. Learn more:

It’s Not Just Medicine

Kate and her crew mates have also worked on the combustion experiments.

Kate has also worked on the Bigelow Expandable Activity Module (BEAM), an experimental expandable capsule that docks with the station. As we work on our Journey to Mars, future space habitats  are a necessity. BEAM, designed for Mars or other destinations, is a lightweight and relatively simple to construct solution. Kate has recently examined BEAM, currently attached to the station, to take measurements and install sensors.

Kate recently performed a harvest of the Plant RNA Regulation experiment, by removing seed cassettes and stowing them in cold stowage.

The Plant RNA Regulation investigation studies the first steps of gene expression involved in development of roots and shoots. Scientists expect to find new molecules that play a role in how plants adapt and respond to the microgravity environment of space, which provides new insight into growing plants for food and oxygen supplies on long-duration missions.

+Plant RNA Harvest

NASA Astronaut Kate Rubins is participating in several investigations examining changes in her body as a result of living in space. Some of these changes are similar to issues experienced by our elderly on Earth; for example, bone loss (osteoporosis), cardiovascular deconditioning, immune dysfunction, and muscle atrophy. Understanding these changes and how to prevent them in astronauts off the Earth may help improve health for all of us on the Earth. In additional, the crew aboard station is also working on more generalized studies of aging.

Mega-tsunamis in Mars's ancient ocean shaped planet's landscape

Giant waves, possibly triggered by two meteorite impacts, may have shaped Mars’s coastline and could hint at whether the red planet was once habitable

Mega-tsunamis in an ancient ocean on Mars may have shaped the landscape and left deposits that hint at whether the planet was once habitable, researchers say.

The giant waves, thought to have reached up to 120 metres in height as they raced over the land, could have been triggered by two large meteorites slamming into the surface.

The tsunamis may been powerful enough to shape much of the ancient coastlines on Mars, said J. Alexis Palmero Rodriguez, of the Planetary Science Institute in Tucson, Arizona, who led the study.

Writing in the journal Scientific Reports, the international team, which included scientists from the US, China and Germany, describe how they set out to probe a Martian mystery.

It has previously been proposed that the lowlands of the northern hemisphere of Mars were catastrophically flooded around 3.4 billion years ago, forming a vast ocean, potentially covering several million square kilometres. But scientists have been puzzled by the lack of an associated shoreline and its expected features.

Now Rodriguez and his team think they may have the answer- the fact that it is hard to make out such ancient shorelines is because huge tsunamis buried them, depositing sediments up to hundreds of kilometres inland.
